The question can be answered on the basis of general transport of proteins.
Answer:
The endomembrane system is present in the eukaryotes that includes the cell organelle that divides them into the structural and functional unit of the cell. This helps in the protein sorting and its transport.
The insulin is the hormone that made of the alpha and beta peptide through the disulfide linkage. The protein must enter in the rough endo plasmic reticulum for the signal recognition and modification of protein. Then the protein moves into the golgi through the vesicles and finally into the endocytosis through the cell membrane.
Because one decaing factor of a cell can cause the cell to breakdown and not work.
